🛡️ BeyckJS - Front end malicious behavior detection plugin

We couldn't find a better name to name it, so we named it Beyck. It is a front-end security script designed to protect the security of site resources, such as detecting screen recording, pasting and copying, media file downloading and saving, script file injection or tampering, browser security interception, dynamic malicious debugging, etc. If you are a commercial website, we recommend that you try to learn about it. Compared with other libraries, it does not have polling, does not hinder the main thread rendering, occupies less memory, and can intelligently detect the open status of development tools. If you also want to learn, try installing it quickly!

🏷️Enable protection

⚠️ This feature involves many detection items, and it is not recommended to enable it in your production environment. Please ensure that it runs under a valid domain name, otherwise it will be considered malicious behavior.

Beyck(function(app) {
	
	//Detected debugging, closing the browser or clearing the page
	app.defend(true);
	
	//Detected debugging jump to specified link
	app.defend('https://xxx.com');
	
	//Real time monitoring and debugging status
	app.defend((state)=>{
		
		if(state){
			console.log('Detected debugging tool running');
		}else{
			console.log('Debugging tool has been closed');
		}
		
	});
	
});

🏷️Customize user keyboard and mouse behavior

⚠️Support selective mouse and button event blocking

Beyck(function(app) {

	//Monitor and handle dangerous button events
	app.onkeys((e) => {
		console.log('Event type', e.type);
		//Do you need protection
		if (e.defend) {
			//Prevent it from continuing to run by rewriting
			e.defend = true;
			console.log('The event has been prevented', e.type)
		}
		console.log('The event has been released', e.type)
	});

});

🏷️Page Launch Lifecycle

⚠Callback events throughout the entire process of application startup

Beyck(function(app) {

	//Protection program starts running or has completed initialization
	app.onentry(function(data) {
		console.log('This is a link passing parameter', data)
	});

	//The application has been loaded completely
	app.onready(function(data) {
		console.log('This is asynchronous cross domain parameter passing', data)
	});

});
